Sub Mare Imperium - Derelict 8-bit
A downloadable game for Windows, macOS, Linux, and Android
About the game
THIS GAME IS FINALLY REACHING IT'S FINAL FORM! PLEASE TRY IT AND REPORT BACK!
This is a 8-bit demake of https://montyontherun.itch.io/sub-mare-imperium-derelict-32-bit for the SEGA Master System and MSX line of computers. I use the exact game core from the 16 and 32-bits versions, but the renderer originally written for the CPC Dev Contest'19. This is actually the project I originally intended to submit for that contest.
Sega Master System
Controls:
- Directions - Walk around (turns only in 90-degrees)
- Fire 1 - Perform action
- Fire 2 - Cycle though the actions to perform
It should be noted that I'm using the legacy video modes from the SG-1000, just like F-16 Fighter; and just like that game, this will not be compatible with Mega Drive/Genesis consoles. This was also forked into a 16-bit version (this fork supports the Mega Drive), featuring more effects: https://montyontherun.itch.io/sub-mare-imperium-derelict-16-bits
MSX computers
Controls:
- Cursor keys - Walk around (turns only in 90-degrees)
- Number keys - perform actions described into the UI
IBM PCs
Controls:
- QWES - Walk around (turns only in 90-degrees)
- Number keys - perform actions described into the UI
This game was written with a big help from https://z88dk.org/ with extensive use of https://github.com/jannone/msx-gfxlib, from Rafael Jannone, which I had the pleasure to work with on a previous day job.

Gonna just leave this here...
On witch system is your fastest running version of this game?
Between MSX and Master System, I don't expect much of a difference. It's the same Z80 with TMS9918 VDP.
Later today, I will upload a version for the IBM PC with 8088 and CGA. That version might perform a little better. Particularly if you run on 10Mhz machines or maybe a 286. On a 486, it might be a bit too fast (but then again, you're better off running the 32-bit version).
The CPC version is back from the dead, fully functional and shaping up greatly. I feel this could be become a really good version!
UI improved!
Thats amazing, how do you create all these versions
I have a common core among the games and different, but slightly intercompatible game engines, all written in C90.

That's an amazing work for game engine users like me. Congratulations!
Adding more features and fixes on the ROM is getting harder and harder!
This is a nice surprise!
...and yet, I shouldn't be surprised...
This is super cool, man
